Answer: 5/19</h3>
=========================================================
Explanation:
There are A = 10 red cards out of B = 10+10 = 20 cards total.
A/B = 10/20 = 1/2 represents the probability of picking a red card.
After that card is selected, there are C = 10 black cards out of D = 20-1 = 19 cards left. The fraction C/D = 10/19 represents the probability of picking a black card where we did not put the first red card back.
Multiply the two fractions we found.
(A/B)*(C/D) = (1/2)*(10/19) = 10/38 = 5/19 is the probability of getting the first card that is red and the second card that is black.
8.5 hours
T = 9 • h (hours worked)
$76.50 = 9 • h
76.50/9 = h
h = 8.5 hours
